Householders will be paid to use less electricity today as three coal plants were ordered to begin warming up in case they are needed for the country's energy supply.
National Grid ESO said it had given the instructions after forecasts showed electricity supply margins may be tighter than normal on Monday. It has also activated a live "demand flexibility service" between 5pm and 6pm today.
This scheme allows the ESO to access additional flexibility when national demand is at its highest during peak winter days. It entitles some households with smart meters to discounts if they cut their use of electricity.
